In other instances, well-known features are omitted or simplified so as not to obscure the invention. However, the following detailed description in conjunction with the drawings will enable one skilled in the art to make and use the present invention even absent the omitted details.

[0023] The purpose of this detailed description being to describe the invention so as to enable one skilled in the art to make and use the present invention, the following description sets forth various specific examples, also referred to as “embodiments,” of the present invention. While the invention is described in conjunction with specific embodiments, it will be understood, because the embodiments are for explanatory purposes only, that this description is not intended to limit the invention to these particular embodiments. Indeed, it is emphasized that the present invention can be embodied or performed in a variety of ways; the detailed description and the drawings do not limit the scope of the invention because the substantive scope of the present invention is to be limited only by the appended claims. The drawings and detailed description are merely representative of particular embodiments of the present invention.

[0024] Reference will now be made in detail to several embodiments of the invention. The various embodiments will be described in conjunction with the accompanying drawings wherein like elements are designated by like alphanumeric characters throughout.

[0025] With reference now to the accompanying drawings, shown in FIG. 1 is a plan view of a preferred embodiment of a foot scrubbing device 10. The foot scrubbing device 10 basically comprises a tank/compartment/receptacle 12, a substantially planar scrubbing surface or cleaning pad 14, a plurality of soap holes 16, and a pump 21.

[0026] The tank 12 is designed to contain liquid soap and/or water. In the preferred embodiments, the tank 12 is plastic and comprises a 2-part mold (shown, e.g., in FIGS. 5 and 6, as top portion 46 and bottom portion 48) that is preferably injection molded. The tank is substantially airtight so as to be pressurized so that the liquid soap can be pumped to the scrubbing surface 14 by the pump 21.

[0027] The surface pad 14 is substantially planar so as to serve as an essentially flat surface upon which to rest the bottom surface of a foot. The shape and size of the surface pad 14 is immaterial as long as the dimensions are such that a foot can be placed thereon. Surface pad 14 may be comprised of any rough material suitable for scrubbing skin. For example, the surface pad 14 may be made of AstroTurf®, sponge rubber, plastic bristles, or the like. In the preferred embodiments, the surface pad 14 is removable and thus serviceable. That is, if the surface pad 14 wears out or otherwise becomes destroyed, the pad 14 can be replaced.

[0028] The plurality of soap holes 16 are the means by which the liquid soap reaches the surface of the surface pad 14. The soap holes 16 are connected to the tops of soap tubes 42 (further described below in conjunction with FIGS. 3 and 4).

[0029] The pump 21 comprises a pump pedal 20, a hinge 18, and a piston 22. In the preferred embodiments, the piston is located below the pedal 20 so that when the user steps on the pedal 20, the piston 22 is compressed. The manner in which the pump 21 works is further discussed below in conjunction with FIGS. 3 and 4.

[0030]FIG. 2 shows an embodiment of the present invention comprising scrubbing posts or toe brushes 24. In the preferred embodiments, there are four scrubbing posts 24 placed in an arc-like formation so as to comfortably fit in between the toes of a foot. Scrubbing posts 24 are preferably substantially vertical-i.e., in a basically upright position. Like the scrubbing pad 14, the scrubbing posts 24 may be formed of any rough material suitable for scrubbing skin. For example, the scrubbing posts 24 may be made of AstroTurf®, sponge rubber, plastic bristles, or the like. As with the scrubbing pad 14, in the preferred embodiments of the present invention, the scrubbing posts 24 are removable and thus serviceable. Also, in the preferred embodiments, the scrubbing pad 14 covers substantially the entire top surface of the device 10 in a continuous manner.

[0031] The foot scrubbing device 10 of the present invention also includes friction means 30 to prevent the device 10 from slipping on a surface such as a shower stall floor or a bathtub floor. In FIG. 2, the friction means 30 are suction cups.

[0032]FIGS. 3 and 4 show cross-sectional views of the foot scrubbing device 10. FIG. 3 shows a cross-section through the soap tubes 42 of one embodiment of the present invention. Shown also is a refill plug 26 that preferably has an o-ring configuration 40. The refill plug 26 allows the user to refill the tank 12 with liquid soap and/or water.

[0033]FIG. 4 shows a cross-section through the center of the device 10 where the pump 21 is located. Note also that FIG. 4 shows the scrubbing posts or toe brushes 24, whereas FIG. 3 does not. This illustrates that, in the preferred embodiments, the scrubbing posts 24 are removable and thus serviceable and replaceable when worn out.

[0034] In operation, a user cleans his or her foot with the foot scrubbing device 10 by placing the foot on the scrubbing surface 14 so that, at least in the embodiments including scrubbing posts 24, the toes are placed in between the scrubbing posts 24. The user then uses his or her other foot to step on the pump pedal 20, thereby causing liquid soap to move to the surface of the pad where the foot is resting. The user then moves his or her foot around so as to enable the scrubbing pad 14 and scrubbing posts 24 to scrub the skin of the foot.

[0035] In the preferred embodiments, the pump 21 includes rubber seals 44 to provide enough pressure in the tank 12 to allow soap (shown, e.g., at 50 in FIG. 8) to be pumped up through the tank 12 to the surface of the surface pad 14. As was mentioned earlier, in the preferred embodiments, the piston 22 is located below the pedal 20 so that when the user steps on the pedal 20, the piston 22 is compressed. Note that the pedal 20 can be designed in accordance with FIGS. 3 and 4. Alternatively, a pedal 20′ can be designed in accordance with FIGS. 7 and 8.

[0036] Note that FIGS. 7 and 8 show an embodiment of the present invention in which a soap tube or channel 42′ is curve-shaped.

[0037] It is emphasized that the present invention may be embodied in various specific forms without departing from the scope of the present invention. For example, the foot scrubbing device 10 may be made of plastic or any other material suitable for wet environments; the shape of the scrubbing pad can be oblong, rectangular, or any other shape suitable for a foot to rest upon; the scrubbing pad can comprise patches of rough material or one integral patch of rough material. In addition, the foot scrubbing device might be used for scrubbing hands; it also might be used with animals as well as humans.

[0038] It is again underscored that the present invention may be embodied in other specific forms without departing from its spirit or essential characteristics. The described embodiments herein should be deemed only as illustrative. Indeed, the appended claims indicate the scope of the invention; the description, being used for illustrative purposes, does not limit the scope of the invention.
